EP93AOFR

Master Bond EP93AOFR is a two component flame retardant epoxy system for bonding, sealing, coating and potting. It has been tested to the standards mentioned above and passes the demanding vertical burn test. EP93AOFR has an easy to use, forgiving, one to one mix ratio by weight. This system has a long open time. The recommended curing schedule for optimizing properties is overnight at room temperature followed by 3-4 hours at 150-200°F. It is a good thermal conductor while retaining a favorable electrical insulation profile.

It bonds well to a variety of substrates including metals, composites, glass, ceramic and many plastics. The service temperature range is -80°F to +300°F. It has reasonably good chemical resistance to water, fuels, oils and many common solvents. The color of Part A is black, Part B is off white and the cured material is black.

EP93AOFR is a specialty product that is used primarily in avionics. Electronic assemblies such as power conversion units, distribution instruments and cooling devices require first rate protection from flames and heat. Also, they often need to transfer heat to avoid damaging components. EP93AOFR is highly effective in conducting heat and providing protection from flames. It should be noted that EP93AOFR is a non-halogenated system, which is highly desirable for handling and environmental issues.
